D'Addario NYXL 038 Single Guitar String

Replacement Electric Guitar String with Enhanced Midrange

The D'Addario NYXL .038" Nickel Wound Single is a single replacement string for electric guitar, part of the NYXL series built with reformulated nickel-plated steel wrap wire wound over a steel core. Round-wound construction produces enhanced midrange frequency response in the 1 – 3.5 kHz range, giving the string more presence and crunch to cut through a dense mix. Compared to traditional nickel wound strings, the NYXL formulation offers higher output and stronger magnetic pickup response, which translates into a brighter, more articulate tone under the fingers. Sold as a single string, this .038" gauge fits the A-string slot on most standard electric guitar sets and is also commonly used as a low A in custom drop-tuned sets. The string is uncoated, so the natural feel and bite of the wrap wire come through immediately.

Who It's For

The D'Addario NYXL .038" Nickel Wound Single is the right choice for electric guitarists who need a single replacement string without buying a whole new set. Players who break one string mid-gig, who want to swap a worn A-string for a fresh one, or who build custom gauge sets from individual strings will find this format practical and economical. The brighter midrange response suits rock, blues, and country styles where the A-string needs to speak clearly through a band mix, and the round-wound surface keeps the familiar textured feel under the pick. Improved tuning stability over standard nickel strings makes it a sensible option for players who bend heavily or run tremolo systems. As part of the NYXL line, it pairs naturally with other NYXL singles when assembling a balanced custom set.
